Abstract

The performance of self-made NJ adsorbent was studied to recover ethylene from industrial off-gas of ethylene oxide (EO) plant by pressure swing adsorption (PSA), focusing on the effects of C₂H₆, CO₂, CH₄, and O₂ on adsorption of C₂H₄. The NJ adsorbent had great PSA stability, except O₂ present in off-gas had some effect on C₂H₄ adsorption. The adsorbent could be regenerated by depressurizing and vacuum degassing. Adsorption capacity of C₂H₄ in C₂H₄-C₂H₆, C₂H₄-CO₂, C₂H₄-CH₄ systems were all above 10 mL/g. The adsorption capacity of C₂H₄ in C₂H₄-CH₄-O₂ was about 7.5 mL/g. The adsorption capacity of C₂H₄ in the off-gas from the EO plant was about 6 mL/g.
